I've dropped one of my remaining three bollocks....and so in all probability this stone should maybe removed from the website...As it is more than likely a rubbing post.
The Dodds, A.E & E.M, even mention it as such in their book "Peakland Roads and Tracks".
So even though the entry for the larger Bradstone on Pastscape.org did mention two stones (one smaller than the other) at roughly this location, it would seem they referred instead to the, 'known missing', standing stone further to the east.
Wirksworth I (Standing Stone / Menhir) — Fieldnotes
Local rumour has it that after 7 years of slumber the Middle Peak Quarry is about to be reworked and even better..... extended. Unfortuantely the stone and, to a much lesser extent, the narrow road that passes it by are likely to be amongst the casualities. An alternative road/route already exists and well the stone.....is just a stone to a lot of folk living in Wirksworth, that is if they know it's there at all.
So along with the extensions to the quarries around Stanton and the recently approved plans to rework and extend the rakes on Longstone Edge it would appear that the Peak is all out to invert itself....
Visited here on Friday 28th October, and unable to locate any stone in the field. However, a small stone very much like the one in the photo was seen on a pile of rubble just through the gateway to the East of this field. Oh dear.
